Don't kid yourself. These guys have the "electorate" figured out just fine. Unfortunately "the electorate" they are pandering too for the most part are the registered republicans who will vote the primary. That's why Hickabee, Cruz et al can hang in there as they will always pick up a big hunk of religious votes.
The problem is that same candidate can't win the general, or even come close. That's why us conservative leaning folks are fucked. Shit I agree with Cruz/Huckabee on more things than Clinton and I'm not sure i could support them.
